BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to marine entertainment and informationsystems. More particularly, the invention relates to a combinationmarine entertainment system and depth sounder that more efficientlyutilizes limited space on a boat instrument panel, that is moreconvenient to operate, and that is more economical to manufacture.

2. Description of the Prior Art

Many boats are outfitted with both entertainment systems and depthsounders. Unfortunately, prior art marine entertainment systems anddepth sounders are manufactured and installed separately in their ownhousings, necessitating the mounting of both devices on or near a boat'sinstrument panel so that both can be easily seen and operated. Thosefamiliar with boats will appreciate that the typical marine instrumentpanel is crowded with a multitude of gauges and instruments and,therefore, space is extremely limited. Another limitation with the priorart practice of manufacturing and installing marine entertainmentsystems and depth sounders separately is that the controls, displays andother components of the devices are duplicated, thus increasing both thecosts to manufacture and the complexity of operating the devices.

Accordingly, there is a need for improved marine entertainment systemsand depth sounders that overcome the limitations of the prior art.

OBJECTS AND SUMMARY OF THE INVENTION

The present invention solves the above-described problems and provides adistinct advance in the art of marine entertainment and informationsystems. More particularly, the present invention provides a combinedmarine entertainment system and depth sounder that more efficientlyutilizes limited marine instrument panel space, that is more convenientand simple to operate, and that shares certain components and,therefore, is less expensive to manufacture and install.

The combined marine entertainment system and depth sounder of thepresent invention broadly includes a housing; an entertainment assemblyincluding a display and an entertainment component positioned in thehousing; and a depth sounder assembly including a depth displaypositioned within the same housing as the entertainment assembly displayand entertainment component.

The entertainment component of the entertainment assembly may be one ormore of the following: a commercial broadcast AM receiver, a commercialbroadcast FM receiver, a NOM weather radio band receiver, a compact discplayer, a digital video disc player, a mini-disc player, a cassette tapeplayer, an audio playback apparatus, a low-level audio input driven byan external audio source, a low-level audio output to drive externalaudio equipment, a digital audio input, a digital audio output; or anyother conventional entertainment device. The depth display is configuredto be coupled with a depth soundertransducer for receiving depthinformation therefrom and for displaying the depth information.

The housing, entertainment assembly, and depth display described abovemake up a main unit of the marine entertainment and informationapparatus. In preferred forms, the apparatus also includes a separateremote unit positioned outside the housing of the main unit andoperatively coupled therewith. The remote unit includes a remotehousing, a remote depth sounderdisplay positioned within the remotehousing for remotely displaying the depth information, and remotecontrols for remotely controlling operation of the entertainmentassembly and the depth sounder assembly.

By constructing a combined marine entertainment system and depth sounderas described herein, numerous advantages are realized. For example, bypositioning components of the entertainment assembly and depth sounderin a common housing that can be mounted in a single opening of a marineinstrument panel, valuable marine cockpit space is saved. Moreover, bycombining the components of the entertainment assembly and depth sounderinto a single unit, displays, controls, and certain other componentsrequired by both devices can be combined, further saving instrumentpanel space and simplifying the operation and use of the devices.Furthermore, the sharing of certain components of the devices reducesthe manufacturing and installation costs of the apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Turning now to the drawing figures and particularly FIG. 3, a marineentertainment system and depth sounder apparatus 10 constructed inaccordance with a preferred embodiment of the present invention isillustrated. The apparatus is configured for mounting in or near aninstrument panel of a marine cockpit as illustrated in FIG. 4 andbroadly includes a main unit 12 and one or more remote units 14.

The main unit 12, which is illustrated in more detail in FIG. 1,includes an outer housing 16, portions of an entertainment assemblyincluding an entertainment component 18 and display 20 positioned in thehousing, and portions of a depth sounder assembly including a display 22also positioned within the housing. The housing is conventional and maybe formed of any conventional material such as synthetic resinmaterials, but is preferably manufactured from high-impact resistantplastic alloys. The housing is preferably similar in size and shape ashousings typically used for automobile stereo systems.

The entertainment component 18 may be a commercial broadcast AMreceiver, a commercial broadcast FM receiver, a NOAA weather radio bandreceiver, a compact disc player, a digital video disc player, amini-disc player, a cassette tape player, an audio playback apparatus, alow-level audio input driven by an external audio source, a low-levelaudio output to drive external audio equipment, a digital audio input, adigital audio output; or any other conventional entertainment devicepositioned in the housing 66.

The entertainment display 20 is positioned in the housing so that it isvisible from the front of the main unit as illustrated in FIGS. 1 and 3.The display is preferably a liquid crystal display (LCD).

The entertainment assembly also includes controls mounted to the housingso that they are visible from the front of the assembly for operatingthe assembly. The controls may include a keypad 24 for presettingcertain information such as radio channels and pushbuttons forconventional features such as power 26, weather band (WX) 28, source(SRC) 30, increase volume (+) 32, decrease volume (−) 34, scan forward(UP) 36, and scan backward (DN) 38.

As illustrated in FIG. 3, the entertainment assembly may also includeexternally mounted speakers 40, a CD changer 42, an antenna 44, a poweramplifier 46, and other conventional entertainment components. Theentertainment assembly is preferably powered by a battery such as thebattery provided in a conventional boat. Operation of certain functionsof the entertainment assembly are performed by an internalmicroprocessor, microcontroller, or other computing device (not shown).

The depth sounder display 22 is also mounted in the housing 16 as bestillustrated in FIG. 1. The display is preferably an LCD. The depthsounder assembly also includes an external depth sounder transducer 50illustrated in FIG. 3. The transducer is preferably a sonic-type depthtransducer but may be any device operable to determine depth informationand to display the depth information in the depth display. The depthsounder assembly may also include controls for controlling operation ofthe assembly and be configured for receiving user-configurable depthoffsets.

In preferred forms, the depth sounder display 22 comprises a portion ofthe entertainment assembly display 20 as illustrated in FIGS. 1 and 3.This permits the depth information to be displayed alongside informationon the entertainment assembly to reduce the number of components in theapparatus and, therefore, reduce space requirements and manufacturingcosts. Similarly, operation of the depth sounder assembly is preferablyaccomplished with the same controls provided with the entertainmentassembly and processing required by the depth sounder assembly may beperformed by the microprocessor or microcontroller provided with theentertainment assembly. A “mode” switch 52 is provided to switch thecontrols between the entertainment assembly and the depth sounderassembly. Once again, the use of common controls and microprocessor ormicrocontroller for the entertainment assembly and the depth sounderassembly reduces the components of the apparatus and, therefore,conserves space and costs.

The remote unit 14, which is best illustrated in FIG. 2, is separatefrom the main unit 12 and is operably coupled therewith. The remote unitmay be coupled with the main unit by conventional wires or cabling ormay alternately communicate with the main unit via wireless transceiverspositioned in both units. The remote unit broadly includes a remotehousing 54, a remote display 56, and remote controls 58. The remote unitmay also include its own microprocessor, microcontrolleror othercomputing device.

The remote housing 54 is preferably sized to fit within a standardmarine instrument opening as illustrated in FIG. 4. The housing may beformed of any conventional material such as synthetic resin materials,but is preferably manufactured from high-impact resistant plasticalloys.

The remote display 56 is provided for remotely displaying theentertainment information and/or the depth information that is alsodisplayed on the main unit 12. The remote display is also preferably anLCD.

The remote controls 58 may include pushbuttons similar to thepushbuttons on the main unit including pushbuttons for features such asweather band (WX) 60, source (SRC) 62, increase volume (+) 64, decreasevolume (−) 66, scan forward (UP) 68, scan backward (DN) 70, mode 72 (forswitching the controls and display between the entertainment assemblyand the depth sounder assembly), mute 74 (for muting or pausing theentertainment assembly), and display 76 (for switching the displaybetween the entertainment assembly and the depth sounder assembly andfor muting a depth sounder alarm).

The apparatus 10 of the present invention may also include additionalremote units (not shown) that may be positioned elsewhere in the boat.For example, the apparatus may include remote units similar to the oneillustrated in FIG. 2 except that the display or the controls may beremoved.

In preferred forms, the depth sounder assembly also includes an alarmcircuit for sounding an audible alarm during certain conditions. Forexample, the alarm circuit may be configured to sound an alarm if thedepth of the body of water being monitored is below a certain thresholdlevel. The audible alarm may be a separate alarm such as a bell or horn,but is preferably sounded over the speakers 40 of the entertainmentassembly. This further reduces the required number of components of theapparatus, saving mounting space and manufacturing and instructioncosts.

In accordance with another aspect of the present invention, theentertainment assembly includes an automatic muting circuit for mutingthe entertainment assembly when the audible alarm of the depth sounderis sounding so that only the depth alarm is heard over the speakers 40.
